Traces of human presence in the area date to the Palaeolithic and Neolithic ages; later it was a Gallo-Roman settlement on the main road from Paris to Sens. The name Corbeil is derived from the Latin Corbulium, from the Gaulish cor beel, meaning "holy house". Since the time of Aymon, comte de Corbeil (died 957), to the 12th century it was the chief town of a powerful county, which passed to Mauger, son of Richard I of Normandy.
William de Corbeil (died 1136) became archbishop of Canterbury, but nothing is known for certain about his parentage.

Peter of Corbeil (died 1222) was the teacher of Lotario de Conti, who became pope as Innocent III.
Representatives of the king of France signed two treaties of Corbeil were signed in the town, the Treaty of Corbeil (1258) between France and Aragon and the Treaty of Corbeil (1326) between France and Scotland.
